Do you know that you can practice rock climbing in Central Park? Yes, you can! The
place to go is Umpire rock! One of the few natural attractions in the Park, this rock
foundation is dated to be between 190 million and 1.1 billion years old.
This ancient bedrock lies under the entire Manhattan, with all the skyscrapers standing
atop of it! It was incorporated to the design of the Greensward plan partly due to the fact
that the rock proved to be very hard to blast.
